Halozyme Inc. currently manages 4 pending office actions in the Biotechnology & Pharmaceuticals technology area. These 4 actions are distributed among 4 distinct examiners and 2 distinct art units. This indicates that while the company is dealing with 4 different individuals, the cases are grouped into only 2 technical areas at the patent office.
The busiest examiner for the company is HOLLAND, PAUL J, who is responsible for 1 pending action. Since each of the 4 distinct examiners is handling exactly 1 of the 4 pending office actions, the workload is evenly spread. Practitioners should focus on the standards of the 2 distinct art units while tailoring their arguments to the individual styles of the 4 distinct examiners involved. The concentration in 2 distinct art units allows for some consistency in the technical narrative across the 4 pending office actions. Success will depend on navigating the individual preferences of the 4 distinct examiners while maintaining a cohesive strategy that aligns with the expectations of the 2 distinct art units that oversee these cases.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §101 + other | 1 (25%) |
| §103 only | 1 (25%) |
| Double-patenting + other | 2 (50%) |
